plotbyfactor: x-y scatterplot, colored by levels of a factor.

In locfit: Local Regression, Likelihood and Density Estimation

x-y scatterplot, colored by levels of a factor.

Description

Produces a scatter plot of x-y data, with different classes given by a factor f. The different classes are identified by different colours and/or symbols.

Usage

plotbyfactor(x, y, f, data, col = 1:10, pch = "O", add = FALSE, lg,
    xlab = deparse(substitute(x)), ylab = deparse(substitute(y)),
    log = "", ...)

Arguments

x	Variable for x axis.
y	Variable for y axis.
f	Factor (or variable for which as.factor() works).
data	data frame for variables x, y, f. Default: sys.parent().
col	Color numbers to use in plot. Will be replicated if shorter than the number of levels of the factor f. Default: 1:10.
pch	Vector of plot characters. Replicated if necessary. Default: "O".
add	If TRUE, add to existing plot. Otherwise, create new plot.
lg	Coordinates to place a legend. Default: Missing (no legend).
xlab, ylab	Axes labels.
log	Should the axes be in log scale? Use "x", "y", or "xy" to specify which axis to be in log scale.
...	Other graphical parameters, labels, titles e.t.c.

Examples
